BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a foldable tent frame, and inparticular to an improved foldable tent frame in which a connectionframe connected to a column is minimized, and a fabrication is verysimple, and a fabrication cost is significantly decreased, and it isvery economical, and a folding operation of tent is easily achieved insuch a manner that a frame engaged to a top connection part is designedto rotate.

[0003] 2. Description of the Background Art

[0004] A conventional tent frame includes a column supporting a tent, aconnection frame connected to each column, and an upper cover thatcovers an upper side of the connection frame for thereby preventingsunlight.

[0005] As shown in FIG. 1, the tent frame according to the presentinvention includes four columns 1 a, 1 b, 1 c and 1 d each having asupport 2 at a lower end of the same wherein the columns areheight-adjustable.

[0006] A top connection part 3 is inserted and engaged to the upper endsof the columns 1 a, 1 b, 1 c and 1 d. A slide connection part 4 isconnected to a lower side of the top connection part 10 wherein theslide connection part 4 is slid up and down along the columns 1 a, 1 b,1 c and 1 d.

[0007] In addition, the top connection part 3 and the slide connectionpart 4 are foldable-connected using a plurality of connection frames 2 aand 2 b, so that four columns 1 a, 1 b, 1 c and 1 d are connected witheach other for thereby forming a single set structure.

[0008] At this time, a plurality of the connection frames 5 a and 5 bare foldable-connected based on a hinge 6 like scissors. An upper jointconnection part 7 connecting the connection frame 5 a engaged to theslide connection part 4 slidable-connected to the columns 1 a, 1 b, 1 cand 1 d, and a lower joint connection part 8 connecting the connectionframe 5 b engaged to the top connection part 3 fixedly connected to theupper ends of the columns 1 a, 1 b, 1 c and 1 d are connected thereto,respectively.

[0009] The upper joint connection part 7 is connected with the topcolumn connection part 9 a engaged with the top column 9, and the lowerjoint connection part 8 is connected with the top column 9 for therebybeing slidably operated. It is connected by a top support part 9 bsupporting the top column 9 and the connection frame 5 d.

[0010] The connection frame 5 c connecting the upper joint connectionpart 7 and the connection frame 5 d connecting the lower jointconnection part 8 and the top support part 9 b are connected by a hinge6 like scissors.

[0011] When folding the same, four columns 1 a, 1 b, 1 c and 1 d getcloser each other, and the top column 3 moves down for therebyminimizing the size, and when unfolding the same, four columns 1 a, 1 b,1 c and 1 d are unfolded, and the top column 3 moves up, and the tent isstably supported.

[0012] As shown in FIG. 2, the top connection part 3 has an engaginggroove 3 a at its center and forms an engaging part 3 c having anengaging hole 3 b at both inner sides of the engaging groove 3 a.

[0013] The connection frame is inserted into the engaging groove 3 a ofthe engaging part 3 c and is fixed using a screw.

[0014] However, in the conventional arty, the connection frames arecomplicated and connected with respect to the top column, so that ittakes a long time to assemble the tent frame, resulting in a largeamount of cost. In addition, since the connection frame is connected tothe top connection part using screws, the frame does not rotate wellduring the folding operation, and the folding work is very inconvenient.

SUMMARY OF THE INVENTION

[0015] Accordingly, it is an object of the present invention to providea foldable tent frame capable of overcoming the problems encountered inthe conventional art.

[0016] It is another object of the present invention to provide afoldable tent frame in which a connection frame connected to a column isminimized, and a fabrication is simple and easy, and a fabrication costis largely decreased, and an economical fabrication is achieved, and acut-away groove is formed in an engaging part of one side of the topconnection part. A rotation protrusion of a rotation part is engaged tothe cut-away groove for thereby achieving an easier installation of therotation part. The rotation protrusion of the rotation part is rotatedalong the surface of the cut-away groove based on a stable and freerotation, so that it is possible to achieve an easier folding operationof the tent.

[0017] To achieve the above objects, in an assembling type tent frame,there is provided a foldable tent frame, comprising a slide connectionpart engaged to a top connection part engaged to the upper ends of fourcolumns slidably at its lower side; lateral upper and lower connectionparts engaged in such a manner that a lateral connection frame engagedin a shape of scissors is folded with respect to the top connection partand the slide connection part; an upper connection part in which a mainconnection frame is engaged, and an end portion of the same is engagedthereto in such a manner that the slide connection part and the laterallower connection part are symmetrical from each other; a support framefixedly installed to support the main connection frame based on the topconnection part and the lateral upper connection part; a connectionframe installed at one surface of the support frame; and an assistantframe of which one end is engaged to the connection frame, and the otherend is engaged to a lower connection part.
